Is "mac address-table notification mac-move" needed for Dynamic Updates to work properly in Campus Manager (LMS 3.1)?

Correct Answer by Joe Clarke about 8 years 9 months ago

The only traps Campus Manager processes are Dynamic UT are cmnMacChangedNotification traps. Therefore, all you need to configure are:


(Under the interfaces)

snmp trap mac-notification change added

snmp trap mac-notification change removed


(Global)

mac address-table notification change

mac address-table notification change interval 15

snmp-server enable traps mac-notification change

snmp-server host HOST COMMUNITY udp-port 1431 mac-notification

One question regarding this when applied to 6500s. I've noticed that the "mac-address-table notification change" and the "mac address-table notification change interval 15" does not work.


Was this command deprecated on the 6500s (tried this on 12.2(18)SXF14)? If so, what's the equivalent replacement?

The change traps are not supported on the 6500s running IOS.

So would that mean, at least for now, that Dynamic User Tracking will not work for 6500s running IOS?

Correct. My best guess on why this is the case is that 6500s are typically not use at the access layer.


Switches which can support Dynamic UT are 3560s, 3550s, 3750s, XLs, 2970s, 2960s, ME3400s, 6Ks running CatOS, and 4Ks running CatOS.

Thanks for the list. I'm a bit surprised by this, but I'll take it up through our account manager.

If the trap is there, UT will support it. It just doesn't have the ability to configure it right now. However, if you manually add the commands to the switch, UT won't care that the traps are coming from a 6500 running IOS.
